Goddess Parvati was turned on by her boyfriend doing the dishes. He was naked and she could not help but look at his ass in detail. She played with it and being adventurous, she fingered him. The fingering soon turned into fucking him in the ass using a dildo. She even tried to fist him. And as she came into contact with his shit, she chose to play with it and that is how they came to have a scat fetish.
